ActionScript 3 Working with Events Custom events with event data



    public class CustomEvent extends Event
        public static const START:String = "START";
        public static const STOP:String  = "STOP";

        public var data:*;

        public function CustomEvent(type:String, data:*,
                                    bubbles:Boolean=false, cancelable:Boolean=false)
            super(type, bubbles, cancelable);

            if (data)
       = data;

To dispatch a custom event:

var dataObject:Object = {name: "Example Data"};

dispatchEvent(new CustomEvent(CustomEvent.START, dataObject))

To listen for custom events:

addEventListener(CustomEvent.STOP, stopHandler);

function stopHandler(event:CustomEvent):void
    var dataObject:* =;
